Pee was a fantastic host!
We stayed in Pee's condo during Songkran, and Pee was very helpful with information about the festival, what would be open and closed, and how to get around. He was also very attentive to our needs and questions throughout our stay, and would answer emails promptly.
The condo is exactly what you see in the pictures. Small by western standards, but more than enough space for a couple to use as a base to explore Bangkok. The condo is newly updated, clean, and functional. Don't miss the pool, it's fantastic.
The location is out a bit from the city center, but the neighborhood is safe and easy to navigate. There doesn't seem to be much food or shopping in the immediate area, but it's a very short walk to the skytrain which will take you straight downtown where you'll find everything you could want.
Overall we had a great stay and would love to stay again next time we're in Bangkok.
